Liquid fraction

The class LiquidFractionMatLaw manages all liquid fraction evolution laws, specific to thixotropic materials. These laws are described below.

:!: Careful: Only works if used with thixotropic materials (ThixoEvpIsoHHypoMaterial or ThixoTmEvpIsoHHypoMaterial).

LashkariEffectiveLiquidFractionMatLaw

Description

Computes the effective liquid fraction feffl, excluding liquid entrapped inside solid grains, which does not contribute to the flow. Liquid fraction fl is computed with Scheil law. Some liquid is released when bonds are broken, so feffl depends on the cohesion degree λ.

feffl=fl[1λ(1fl)]
